Eminent academicians from various educational institutions and school teachers participated in the deliberations held in the Seminar Hall of the Happy School. Most speakers were of the opinion that the ‘No detention Policy’ was not conducive to proper grounding of children who, as a result of this, found it difficult to cope up with studies in higher classes. Those who supported the policy advocated for its continuance, citing the inordinate pressure of performing well, that discouraged young children from studies.

श्रीगंगानगर, 8 जुलाई
पुरानी आबादी में विनोबा नगर की अधिकांश सड़कें व गलियाँ गन्दी हैं। सफाई कर्मचारी अपना कार्य नहीं करते हैं। गड्ढे पानी से भरे हुए हैं। नालियाँ बन्द हैं और पानी ऊपर से होकर बह रहा है। वहाँ हर तरफ कचरे के ढेर लगे हैं। पूरा विनोबा नगर मच्छरों से भरा है। इस क्षेत्र में सफाई की समस्या बार-बार होती है। वर्षा का मौसम भी आ रहा है। बारिश के दिनों में समस्या और भी गंभीर हो जाती है। किसी भी समय कोई भी दुर्घटना हो सकती है। यदि सम्बन्धित अधिकारियों द्वारा तुरन्त आवश्यक कदम नहीं उठाये गये तो कोई भी महामारी फैल सकती है। इस क्षेत्र के निवासी बहुत मुश्किल में हैं।

Power Failure in Gadara
(by Anuradha – reporter)

Gadara, February 21
Power failure in Gadara has disturbed the daily life of the villagers. No work can be done without electricity. There is no water supply due to it. It is the time of examination but students cannot study without electricity. Sometimes the light goes off for several hours and if there is light, there are ups and downs in the voltage. Many electric appliances have been damaged by the high voltage. On the other hand, no electric appliance works properly due to low voltage. Power fails not only during the day but also at night. So there are possibilities of theft and accidents. Repeated complaints have been made to the concerned higher authorities but no action has been taken yet.

गदारा, 21 फरवरी
विद्युत व्यवधान ने गडरा के दैनिक जीवन को अस्त व्यस्त कर दिया है। बिजली के बगैर कोई भी कार्य नहीं किया जा सकता है। इसकी वजह से जलापूर्ति भी नहीं हो पाती है। यह परीक्षा का समय है लेकिन बिजली के बगैर विद्यार्थी पढ़ भी नहीं सकते हैं। कभी-कभी बिजली कई घण्टों के लिए चली जाती है और यदि बिजली आती भी है तो वोल्टेज में उतार चढ़ाव होता है। उच्च वोल्टेज के कारण कई सारे विद्युत उपकरण नष्ट हो गये हैं। दूसरी ओर कम वोल्टेज की वजह से कई सारे विद्युत उपकरण सही प्रकार से काम नहीं करते हैं। बिजली ना केवल दिन को बल्कि रात को भी जाती है। इसलिए चोरी व दुर्घटनाओं की सम्भावना रहती है। संबंधित उच्चाधिकारियों को कई शिकायतें की गई लेकिन कोई लाभ नहीं हुआ।
